Electric Characteristics - LG HM031M Engineering Product Data Book

10. Electric characteristics

Circuit breaker specification
• Select a power source that is capable of supplying the current required by the unit.
• Use a recognized circuit breaker between the power source and the unit.
A disconnection device to adequately disconnect all supply lines must be fitted.
• Applying below specification of breaker is recommended.
• Separate main power supply and heater supply.

• DHW Heater : Domestic Hot Water tank heater
Notes:
1. Voltage range Voltage supplied to the unit terminals should
be within the minimum and maximum range.
2. Maximum allowable voltage unbalance between phase is 2 %.
3. MCA could be replaced to the maximum operating input
current. Select wire spec. based on the MCA.
4. MFA is used to select the circuit breaker and ELCB(Earth
Leakage Circuit Breaker). Recommended circuit breaker is
ELCB.
5. RLA are measured as the test condition.
